| 摘 要： | 对于许多便携式数据记录系统，虽然系统大部分时间处于睡眠状态，但这样仍消耗一定的能量。为了进一步降低系统功耗，特设计一电源开关电路，可使单片机系统平时处于关闭状态，定时开启时系统上电，进行数据采集，一次工作结束时单片机关闭开关，系统断电。

| Abstract: | For many portable data recording systems they are in sleep at most of time but they still consume energy .In order to cut down the power consumption,we designed a switching-circuit. With it the system is closed at ordinary time. When the timing-circuit given alarm the system will be powered on.After work done the computer would close the switching-circuit the power of this system turned off. |
